The present paper is meant to be a short presentation of the actual stage of nanomaterials used in dentistry. It shows some theoretical considerations regarding characteristics of some nanomaterials used in dentistry. In recent years, increasing demands for dental reconstruction have led to the development of new materials that have multiple applications in dental medicine and which must meet aesthetic requirements, biocompatibility requirements as well as hardness or durability. Surpassing the extraction period, dentistry has entered the "restorative era" in which it is desirable to introduce new materials that will lead to the most natural restorations with the physical and chemical properties closest to those of the dental tissues. The discovery of such materials has become a definite necessity in order to achieve consistent progress in this respect. Interest in using nanomaterials, composites with nanomaterials in restorative dentistry, as well as reconstruction, is constantly increasing. It is therefore important that the mechanical and other properties of these materials be carefully studied and especially improved. The aim of this research is to help dentists, by analyzing and describing existing composite nanomaterials and by widening their area of use of in restorative dentistry, and improving their characteristics.
